mid-1918. These later models were used on almost all late-war German fighters, and its only real competition, the <a href="/wiki/BMW_III" class="mw-redirect" title="BMW III">BMW III</a>, was available only in very limited numbers.

Like most inlines of the era, it used a large aluminium crankcase as the main structural component, with separate cylinders made from steel bolted onto it. The technology for screwing a threaded cylinder of steel into an aluminium crankcase did not exist at that time. Jackets for cooling water covered the top 2/3 of the cylinder, feeding a radiator via connections at the back of the engine. The only obvious design change from the earlier D.II was to use separate cooling jackets for each cylinder, whereas the D.II used one jacket each for a trio of adjacent pairs of cylinders. </p><p>The D.III featured a rather prominent <a href="/wiki/Overhead_camshaft#Single_overhead_camshaft" class="mw-redirect" title="Overhead camshaft">overhead cam</a> operating the single intake and exhaust valves, powered by a shaft running up from the <a href="/wiki/Crankshaft" title="Crankshaft">crankshaft</a> at the rear of the engine. Ignition was provided by <a href="/wiki/Dual_ignition" title="Dual ignition">two sets of spark plugs</a>, one located on either side of the cylinders, each powered by a separate <a href="/wiki/Ignition_magneto" title="Ignition magneto">magneto</a> for redundancy. The ignition cables were protected in tubes running down either side of the cylinders.

While it saw widespread use in early examples of the C-series of two-seat general-purpose biplanes, the D.III was too large for contemporary fighter designs and did not see use in that role. At the time, fighters were generally powered by lighter rotary engines of power output levels from 60 kW (80 hp) to about 82 kW (110 hp), or by water-cooled inline engines in the 75 kW (100 hp) to 89 kW (120 hp) range such as the earlier <a href="/wiki/Mercedes_D.II" title="Mercedes D.II">Mercedes D.II</a>. By 1916 new designs had grown in size and performance and the D.III became popular on new designs. By 1917 the D.III was being widely used in fighters, most notably on the famous <a href="/wiki/Albatros_D.I" title="Albatros D.I">Albatros D.I</a>. Production of this version was essentially wound down by May 1917, with only a handful continuing to be delivered until October. British HP ratings being slightly different (with 746 watts = 1 hp) to the German PS or <a href="/wiki/Horsepower#Metric_horsepower_(PS,_cv,_hk,_pk,_ks,_ch)" title="Horsepower"><i>Pferdestärke</i></a> standard of roughly 735 watts per PS horsepower, it is probable that this engine would have had a slightly higher rating under British HP numbers. Fuel consumption was 11.75 gallons per hour.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> Its compression ratio was 4.5:1.<sup id="cite_ref-:0_3-0" class="reference"><a href="#cite_note-:0-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> </p><p>Development of the basic design led to the slightly modified 130 kW (170 hp) <b>D.IIIa</b>, which took over on the production lines in June 1917. The main change was to change the piston profile to have a flat head instead of the former concave one, thereby slightly increasing maximum compression to 4.64:1.<sup id="cite_ref-:0_3-1" class="reference"><a href="#cite_note-:0-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> Other changes were mainly in design details, notably a redesigned crankcase and new carburetor. Many of the accessories were also redesigned or moved around on the engine. This model was produced only briefly, for use on the <a href="/wiki/Albatros_D.III" title="Albatros D.III">Albatros D.III</a> but there are indications that possibly some early Albatros (Alb.) made Fokker D.VII's were also equipped but probably had the engines upgraded or replaced as quickly as possible. This engine has been referred to in postwar British analysis as generating 130 kW (180 hp) </p><p>A more "radical" upgrade was the 130–150 kW (180–200 hp) <b>D.IIIaü</b>, introduced in late 1917, the D.IIIaü was a standardized refinement of the D.III and D.IIIa design and the ü designation was never official. This engine changed the pistons again, this time to a domed profile that further increased the maximum compression – the ü was for "über", meaning "overcompressed". Additionally, a new altitude-compensating carburetor was added, which improved performance at higher altitudes. To support operations at these altitudes, water from the radiator was used to heat the air intake and prevent icing in the carburetor. The aü model, which included upgraded D.III and D.IIIa engine blocks, was the most prolific German fighter engine of 1918 and designed into most fighter designs from late 1917 on. This included most of the entries in the First Fighter Competition at <a href="/wiki/Adlershof" title="Adlershof">Adlershof</a> in January 1918, notably the famed <a href="/wiki/Fokker_D.VII" title="Fokker D.VII">Fokker D.VII</a>. In British post war evaluation the D.IIIaü demonstrated 150 kW (200 hp) according to the British standards. </p><p>A final version attempting to keep the D.III block competitive was the 150 kW (200 hp) (149–162 kW (200–217 hp)) <b>D.IIIav</b> (or avü), introduced mid-October 1918. The av used slightly longer pistons made of aluminium (possibly a first for a production engine), increasing the compression yet again, while at the same time allowing them to move faster due to the reduced weight. The maximum allowable RPM increased from 1,400 in the earlier models to 1,600 in the av, accounting for most of the gains in power. It is unclear if any av's saw service use. The increased use of <a href="/wiki/Benzene" title="Benzene">Benzol</a> in German aviation fuel may have helped this final upgrade of power, its higher octane rating being better suited for the higher compression ratio. </p> <div class="mw-heading mw-heading3"><h3 id="External_differences_between_models">External differences between models</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Mercedes_D.III&action=edit&section=3" title="Edit section: External differences between models"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size mw-halign-left" typeof="mw:File/Thumb"><a href="/wiki/File:Early_Mercedes_D_III_Valvetrain.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/2/2c/Early_Mercedes_D_III_Valvetrain.jpg/220px-Early_Mercedes_D_III_Valvetrain.jpg" decoding="async" width="220" height="136" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/2/2c/Early_Mercedes_D_III_Valvetrain.jpg/330px-Early_Mercedes_D_III_Valvetrain.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/2/2c/Early_Mercedes_D_III_Valvetrain.jpg/440px-Early_Mercedes_D_III_Valvetrain.jpg 2x" data-file-width="1058" data-file-height="654" /></a><figcaption>Aft-end details of the original <a href="/wiki/SOHC" class="mw-redirect" title="SOHC">SOHC</a> valvetrain for the D.III - the rocker arm emerges from the "rocker box" through a slot in the box's side.</figcaption></figure> <p>All of the D.III series were generally very similar to other models, with the exception of the piston profile, carburetor details and valvetrain details. It appears that upgrades were available for many of the engines, certainly for the III to IIIa, and IIIa to IIIaü. It would seem unlikely that early III's would ever make it to the IIIaü standard, as they would almost certainly have been worn out in service before then. </p><p>The valvetrain changes concerned the layout of the rocker arms that operated the valves. Early models had square <a href="/wiki/Rocker_cover" title="Rocker cover">rocker boxes</a> positioned directly over the cylinders with the rocker arms exiting through vertical slots, one cut into each of the opposing sides of the boxes, as shown at left.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> The earlier "side-slot" rocker arm design had also been used for the Mercedes D.I and D.II engines' valvetrains. In later versions of the D.III engines, the boxes were relocated rearward on the tubular camshaft housing, and the now easily sealable cylindrical rocker arm shafts protruded forwards through the front surfaces of the boxes, operating the now fully exposed rocker arms with the exposed shaft ends, as shown at right.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> </p> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Later_Mercedes_D_III_Valvetrain.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/d/d5/Later_Mercedes_D_III_Valvetrain.jpg/220px-Later_Mercedes_D_III_Valvetrain.jpg" decoding="async" width="220" height="135" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/d/d5/Later_Mercedes_D_III_Valvetrain.jpg/330px-Later_Mercedes_D_III_Valvetrain.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/d/d5/Later_Mercedes_D_III_Valvetrain.jpg/440px-Later_Mercedes_D_III_Valvetrain.jpg 2x" data-file-width="1004" data-file-height="615" /></a><figcaption>Later pattern SOHC D.III valvetrain, using the relocated rocker box design, with rotary shafts to operate the fully exposed <a href="/wiki/Roller_rocker" class="mw-redirect" title="Roller rocker">roller rocker</a> arms.</figcaption></figure> <p>The newer arrangement was stated as being interchangeable as a set with the complete camshaft, rocker boxes, rocker arms and valve springs, with the D.III's earlier "side-slot" cam drive system design - the later system seems to have influenced both <a href="/wiki/Packard" title="Packard">Packard</a>'s and <a href="/wiki/Hall-Scott" title="Hall-Scott">Hall-Scott</a>'s engine designers to adopt a nearly identical "slotless" rocker-box overhead cam valvetrain design feature for the <a href="/wiki/Liberty_L-12" title="Liberty L-12">Liberty L-12</a> <a href="/wiki/Allies_of_World_War_I" title="Allies of World War I">Allied</a> V-12 aviation engine. </p><p>Confusingly, the "ü" was not an official part of the name. This leads to a number of problems in various references, which often confuse the IIIa with the IIIaü, listing the former as a 130 kW (180 hp) engine. There are two D.IV engines — from the <i><a href="/wiki/IdFlieg" class="mw-redirect" title="IdFlieg">IdFlieg</a></i> aircraft powerplant class designations based on power output — one <a href="/wiki/Mercedes_D.IV" title="Mercedes D.IV">the straight-eight</a> based on the 140 mm bore D.III pistons; and the later, six-cylinder <a href="/wiki/Mercedes_D.IVa" title="Mercedes D.IVa">Mercedes D.IVa</a> with 160 mm bore cylinders, which was essentially unrelated. </p><p>The D.III line of engines would find themselves eclipsed in performance by the <a href="/wiki/BMW_IIIa" title="BMW IIIa">BMW IIIa</a> of 138 kW (185 hp) and then 150 kW (200 hp)(British rated it at 170 kW (230 hp)) in 1918, however, the small number of BMW's produced ensured that the Mercedes D.III series would be the primary German fighter engine up to the last month or two of the war and it would still be seen in very large numbers even at the end. At the end of the war the D.IIIaü would still be the numerically predominant German fighter engine. As a result, the Fokker D.VII's (those not equipped with BMW IIIa's) and the Pfalz D.XII's would be engine-limited in performance (as opposed to "airframe-limited") and yet would still be formidable adversaries to their Allied counterparts. The D.IIIaü was considered the optimum engine for the Roland D.VI, Pfalz D.IIIa, and Albatros D.Va fighters, whose airframes were of an earlier, "all-wood" generation in design. </p> <div class="mw-heading mw-heading2"><h2 id="Variants">Variants</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Mercedes_D.III&action=edit&section=4" title="Edit section: Variants"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <dl><dt>Mercedes F1466</dt> <dd>Company designation for the D.III</dd> <dt>D.III</dt> <dd>The original production version directly developed from the <a href="/wiki/Mercedes_D.II" title="Mercedes D.II">Mercedes D.II</a> developing 110–120 kW (150–160 hp)</dd> <dt>D.IIIa</dt> <dd>An up-graded D.III introduced in 1917 rated at 130 kW (170 hp)</dd> <dt>D.IIIaü</dt> <dd>An unofficial designation, (ü for über), for D.IIIa engines with domed pistons, operating "over-compressed", (at a higher compression ratio).
